How Is Your PQube Different?
There are many power quality meters, energy meters, and energy recorders available. What
makes the PQube stand out from other products?
No software. No rental fees. Open data. -- You don’t need any software from PSL to use
the PQube. Do you have a web browser? A text editor? A spreadsheet program like
Microsoft Excel®? That’s all you need! All the data that the PQube records are in open
formats that are easy to understand. You don’t have to buy or lease software from Power
Standards Lab, you don’t have to pay us to see your data, and the files are easy to pass on
to third parties.
Friendly data. – When you look at information about your electric power, you don’t want
to spend a lot of time learning to use software to get the view that you want. You simply
want your data organized and presented to your in a format you can understand. Your
PQube presents power quality events, trends, and statistics in formats you can easily use
and lays the data out in a way that’s understandable. Your PQube knows what’s
important.
Free firmware updates – From time to time, we offer firmware updates to add new
features to your PQube. Other instrument manufacturers charge for firmware updates, we
don’t.
Works out of the box, or configure everything to work for you – With our patent-pending
auto configuration, you can connect your PQube to the power that you want to measure
and the PQube will immediately start recording data. If you don’t like the default settings
you can change almost any setting in the PQube Configurator program, or by editing a text
file on the SD card.
Works with or without a network – Do you have an Ethernet network? Use an optional
ETH1 module and get emails when an event occurs, browse the recorded events and
trends with your web browser, or integrate it into your Modbus system. Don’t have a
network? No problem, just walk up to the PQube and take the SD card. You can look at all
the files on any computer (you don’t need software). You don’t need a sophisticated
centralized data collection system to get started. Just connect a PQube and start getting
data right away.
Store years of data on standard SD cards. – Your PQube comes with a 4GB SD card which
will store about 2 years’ worth of data.
Small size – The PQube is tiny (a little bit bigger than your fist), and that makes it easier to
integrate into your product.
Low cost – At Power Standards Lab, we’re experts at building power sensor electronics.
We know how to do it right, and we know how to do it inexpensively. The PQube costs far
less than comparable instruments.
It’s everything you need. – Power quality data: dips, swells, frequency variation, and high-
frequency impulses. Energy data: kWh, kVAh, and carbon. Trend data: daily, weekly, and
monthly strip charts, cumulative probability and load duration. Why buy multiple meters
when the PQube can do it all?
